It is completely normal. Babies in the womb are in a curled up position and tend to be curl for a few weeks post delivery. They will be able to get more upright when they are able to sit un supported and legs will straighten when they can stand on their own. It is recommended that you do not make them stand with weight on limbs unless they are ready.
